Google's Brillo is now Android Things with the first releases now available (though it is a developer preview with several known bugs) and it is going open source. I wonder what kind of impact this will have on HA and how adoptable the protocols will be by existing hardware manufacturers. I am not sure the requirements for "thread" either Google' Thread or Nest's; which are different things right now...; but are being merged in the near future, and how those requirements compare to existing protocols.
